On the stability of solutions to random optimization problems under small perturbations
Abstract/Contents
- Abstract
- Consider the Euclidean traveling salesman problem with n random points on the plane. Suppose that one of the points is shifted to a new random location. This gives us a new optimal path. Consider such shifts for each of the n points. Do we get n very different optimal paths? In this work, we show that this is not the case --- in fact, the number of truly different paths is bounded as n becomes large. The proof is based on a general argument which allows us to prove similar stability results in a number of other settings, such as branching random walk, the Sherrington--Kirkpatrick model of mean-field spin glasses, the Edwards--Anderson model of short-range spin glasses, and the Wigner ensemble of random matrices.
